well, let's hope you haven't wasted more than just that 6 months. nowadays, the locals are much smarter or shall i say vendictive than, say 10 years ago. they might try to blacklist you, if you have a work permit with the company. that could mean that you won't be able to work for the same company anywhere on mailand and then i could also mean that you may not be able to obtain a new work permit in the province of guangdong or even elsewhere in china. don't shoot me please..i'm just showing you the whole picture of the local trends.
all the best to you
and
cheers and beers to all
